Marie Curie’s century-old notebooks are still radioactive, so they’re kept in lead-lined boxes for protection against radiation exposure.

Anyone wishing to handle her notebooks, personal effects, or other items have to wear protective gear and sign a liability waiver, just in case. She basically walked around carrying radium and polonium in her pockets, so… yeah.

Marie and her husband Pierre are buried in Paris’s Panthéon, a mausoleum in that contains the remains of distinguished French citizens — including philosophers Rousseau and Voltaire.


A heart broken mother had this grave designed for her deceased 10-year-old daughter in 1871. While she was alive, the daughter was terrified of storms. The grave was constructed with an entrance that descends to the level of the coffin. Her mother would come and enter the tomb during storms to comfort her child.
